Reference please. If you're adding smartphones getting sold, I doubt it. It's not even close.
In Q2 2011 the numbers of PCs sold was ~ 85 million [1]. The growth rate over Q2 2010 is predicted to be only 2.3 %
For the same Q2 2011 - 428.7 million mobile devices have been sold, out of which 107 million were smartphones [2]. More interesting however is the growth rate of smartphones sales since Q2 2010: 74%
Now, the total number of Windows computers is bigger than all smartphones combined. However, Windows XP still has over 30% market share and Vista has over 10%. That's pretty bad for Microsoft. PCs aren't selling like they used to and users aren't upgrading much.
If Microsoft relies on tablet sales for increasing the numbers of devices with Windows 8, well you can probably count the millions of iPads sold on one hand (correction: according to Wikipedia since April 2010 that's 39.85 million - pretty good, however a small number compared to smartphones). You can also make a case that Microsoft will do deals with hardware makers, however there are good reasons why Android is so far unsuccessful on tablets and I'm not seeing Microsoft doing a better job.
